Because one object can have more things in it. I learned it a t school today.
Answer:
Because there is less energy at higher trophic levels
Explanation:
- In a food chain that shows the feeding levels of organisms in an ecosystem, energy decreases as you move from the lowest trophic level to the highest trophic level.
- The lowest trophic level consists of producers which have the highest energy as they trap energy directly from the sunlight.
- The energy is lost from one trophic level to the next up to the highest trophic level which has the lowest energy.
- Therefore, organisms at the highest trophic level are fewer in number but large in size.
"with the wind" is a tail-wind, and the speeds are added to get the groundspeed.
"against the wind" is a head-wind, and the windspeed is subtracted from the airspeed.
Given: Velocity of light c = 3.00 x 10⁸ m/s
Frequency f = 7.65 x 10⁷/s
Required: Wavelength λ = ?
Formula: λ = c/f
λ = 3.00 x 10⁸ m/s/7.65 x 10⁷/s
λ = 3.92 m
